Abstract
Disclosed is a support structure, such as a liner hanger, for use in a well, including an assembly of slips for wedging to the interior surface of the surrounding well, but maintained off of wedging surfaces in a running in configuration by a drag assembly and latch mechanism connected to the hanger body carrying the wedges. As the latch is configured to permit setting of the support structure, a lost motion coupling joining the slip assembly with the drag and latch assembly permits rotational and limited longitudinal movement therebetween as the slip system moves rotationally, and possibly longitudinally to a limited extent, with the hanger body relative to the drag assembly.
